Configuration Overview
NOTE: This document uses the term preprovisioning in the context of preparing or preconfiguring
entities such as chassis slots, line cards (or Control Forwarding Module (CFM/IOM) cards), MDA
carrier modules (MCMs), media dependent adapters (MDAs), compact media adapters (CMAs),
ports, and interfaces, prior to initialization. These entities can be installed but not enabled. When
the entity is in a
no shutdown
state (administratively enabled), then the entity is considered to
be provisioned .
Alcatel-Lucent 7710 SR routers provide the capability to configure chassis slots to accept specific
line card and MDA types and set the relevant configurations before the equipment is actually
installed. The preprovisioning ability allows you to plan your configurations as well as monitor
and manage your router hardware inventory. Ports and interfaces can also be preprovisioned.
When the functionality is needed, the card(s) can be inserted into the appropriate chassis slots
when required.
The following sections are discussed.
• Chassis Slots and Cards on page 18
• MDAs on page 19
• MCMs on page 19

Chassis Slots and Cards
To pre-provision a chassis slot, the line card type must be specified as well as the MDA/CMA
type. System administrators or network operators can enter card type information for each slot,
allowing a range of card types in particular slots. From the range of card types, a card and
accompanying MDAs/CMAs are specified. When a card is installed in a slot and enabled, the
system verifies that the installed card type matches the allowed card type. If the parameters do not
match, the card remains offline. A preprovisioned slot can remain empty without conflicting with
populated slots.
